Abdominal surgical site infections (SSIs) are infections that occur after abdominal surgery. They can be superficial, involving the skin tissue only, or more profound, involving deeper skin tissues including organs and implanted materials. Currently, SSIs are large global health problem with an incidence that varies significantly depending on the United Nations' Human Development Index. The purpose of this review is to provide a practical update on the latest available literature on SSIs, focusi ...[more]

Project description:Surgical-site infections (SSIs) occur in 2-5% of patients undergoing surgery in the US alone, impacting 300 000-500 000 lives each year, and presenting up to 11 times greater risk of death compared to patients without SSIs. The most common cause of SSI is Staphylococcus aureus, and methicillin-resistant S. aureus (MRSA) is the most common pathogen in community hospitals. Current clinical devices used for approximating incisions and traumatic lacerations include sutures, adhesives, tapes, or staples with or without antimicrobial incorporation. However, current closure technologies may not provide adequate protection against infection, are susceptible to wound dehiscence, and can result in delayed biomechanical recoveries. Laser-activated tissue repair is a sutureless technique in which chromophore-loaded sealants convert laser light energy to heat in order to induce rapid tissue sealing. Here, we describe the generation and evaluation of laser-activated sealant (LASE) biomaterials, in which, indocyanine green (ICG), an FDA-approved dye, was embedded in a silk fibroin matrix and cast into films as wound sealants. Silk-ICG films were subjected to different near-infrared (NIR) laser powers to identify temperatures optimal for laser sealing of soft tissues. A mathematical model was developed in order to determine the photothermal conversion efficiency of LASEs following laser irradiation. NIR laser activation of silk-ICG LASEs increased the recovery of skin biomechanical strength compared to sutured skin in full-thickness incisional wounds in immunocompetent mice, and live animal imaging indicated persistence of silk-ICG LASEs over several days. LASEs loaded with the antibiotic vancomycin demonstrated higher efficacies for combating MRSA infections in a mouse model of surgical site infection compared to antibacterial sutures. Our results demonstrate that LASEs can be loaded with antimicrobial drugs and may serve as new multifunctional biomaterials for rapid tissue sealing, repair and surgical site protection following surgery.

Project description:ImportanceWorld Health Organization guidelines recommend administering surgical antimicrobial prophylaxis (SAP), including cefuroxime, within 120 minutes prior to incision. However, data from clinical settings supporting this long interval is limited.ObjectiveTo assess whether earlier vs later timing of administration of cefuroxime SAP is associated with the occurrence of surgical site infections (SSI).Design, setting, and participantsThis cohort study included adult patients who underwent 1 of 11 major surgical procedures with cefuroxime SAP, documented by the Swissnoso SSI surveillance system between January 2009 and December 2020 at 158 Swiss hospitals. Data were analyzed from January 2021 to April 2023.ExposuresTiming of cefuroxime SAP administration before incision was divided into 3 groups: 61 to 120 minutes before incision, 31 to 60 minutes before incision, and 0 to 30 minutes before incision. In addition, a subgroup analysis was performed with time windows of 30 to 55 minutes and 10 to 25 minutes as a surrogate marker for administration in the preoperating room vs in the operating room, respectively. The timing of SAP administration was defined as the start of the infusion obtained from the anesthesia protocol.Main outcomes and measuresOccurrence of SSI according to Centers for Disease Control and Prevention definitions. Mixed-effects logistic regression models adjusted for institutional, patient, and perioperative variables were applied.ResultsOf 538 967 surveilled patients, 222 439 (104 047 men [46.8%]; median [IQR] age, 65.7 [53.9-74.2] years), fulfilled inclusion criteria. SSI was identified in 5355 patients (2.4%). Cefuroxime SAP was administered 61 to 120 minutes prior to incision in 27 207 patients (12.2%), 31 to 60 minutes prior to incision in 118 004 patients (53.1%), and 0 to 30 minutes prior to incision in 77 228 patients (34.7%). SAP administration at 0 to 30 minutes was significantly associated with a lower SSI rate (adjusted odds ratio [aOR], 0.85; 95% CI, 0.78-0.93; P < .001), as was SAP administration 31 to 60 minutes prior to incision (aOR, 0.91; 95% CI, 0.84-0.98; P = .01) compared with administration 61 to 120 minutes prior to incision. Administration 10 to 25 minutes prior to incision in 45 448 patients (20.4%) was significantly associated with a lower SSI rate (aOR, 0.89; 95% CI, 0.82-0.97; P = .009) vs administration within 30 to 55 minutes prior to incision in 117 348 patients (52.8%).Conclusions and relevanceIn this cohort study, administration of cefuroxime SAP closer to the incision time was associated with significantly lower odds of SSI, suggesting that cefuroxime SAP should be administrated within 60 minutes prior to incision, and ideally within 10 to 25 minutes.

Project description:Antimicrobial stewardship programs (ASPs) focus on improving the utilization of broad spectrum antibiotics to decrease the incidence of multidrug-resistant Gram positive and Gram negative pathogens. Hospital admission for both medical and surgical intra-abdominal infections (IAIs) commonly results in the empiric use of broad spectrum antibiotics such as fluoroquinolones, beta-lactam beta-lactamase inhibitors, and carbapenems that can select for resistant organisms. This review will discuss the management of uncomplicated and complicated IAIs as well as highlight stewardship initiatives focusing on the proper use of broad spectrum antibiotics.

Project description:BACKGROUND:Surgical site infections (SSIs) are highly prevalent in abdominal surgery despite evidence-based prevention measures. Since guidelines are not self-implementing and SSI-preventive compliance is often insufficient, implementation interventions have been developed to promote compliance. This systematic review aims to identify implementation interventions used in abdominal surgery to prevent SSIs and determine associations with SSI reductions. METHODS:Literature was searched in April 2018 (Medline/PubMed and Web of Science Core Collection). Implementation interventions were classified using the implementation subcategories of the EPOC Taxonomy (Cochrane Review Group Effective Practice and Organisation of Care, EPOC). Additionally, an effectiveness analysis was conducted on the association between the number of implementation interventions, specific compositions thereof, and absolute and relative SSI risk reductions. RESULTS:Forty studies were included. Implementation interventions used most frequently ("top five") were audit and feedback (80% of studies), organizational culture (70%), monitoring the performance of healthcare delivery (65%), reminders (53%), and educational meetings (45%). Twenty-nine studies (72.5%) used a multimodal strategy (≥3 interventions). An effectiveness analysis revealed significant absolute and relative SSI risk reductions. E.g., numerically, the largest absolute risk reduction of 10.8% pertained to thirteen studies using 3-5 interventions (p < .001); however, this was from a higher baseline rate than those with fewer or more interventions. The largest relative risk reduction was 52.4% for studies employing the top five interventions, compared to 43.1% for those not including these. Furthermore, neither the differences in risk reduction between studies with different numbers of implementation interventions (bundle size) nor between studies including the top five interventions (vs. not) were significant. CONCLUSION:In SSI prevention in abdominal surgery, mostly standard bundles of implementation interventions are applied. While an effectiveness analysis of differences in SSI risk reduction by number and type of interventions did not render conclusive results, use of standard interventions such as audit and feedback, organizational culture, monitoring, reminders, and education at least does not seem to represent preventive malpractice. Further research should determine implementation interventions, or bundles thereof, which are most effective in promoting compliance with SSI-preventive measures in abdominal surgery.

Project description:The emergence of resistant pathogens is a burden on mankind and threatens the existence of our species. Natural and plant-derived antimicrobial agents need to be developed in the race against antibiotic resistance. Nanotechnology is a promising approach with a variety of products. Biosynthesized silver nanoparticles (AgNP) have good antimicrobial activity. We prepared AgNPs with trans-cinnamic acid (TCA) and povidone-iodine (PI) with increased antimicrobial activity. We synthesized also AgNPs with natural cinnamon bark extract (Cinn) in combination with PI and coated biodegradable Polyglycolic Acid (PGA) sutures with the new materials separately. These compounds (TCA-AgNP, TCA-AgNP-PI, Cinn-AgNP, and Cinn-AgNP-PI) and their dip-coated PGA sutures were tested against 10 reference strains of microorganisms and five antibiotics by zone inhibition with disc- and agar-well-diffusion methods. The new compounds TCA-AgNP-PI and Cinn-AgNP-PI are broad spectrum microbicidal agents and therefore potential coating materials for sutures to prevent Surgical Site Infections (SSI). TCA-AgNP-PI inhibits the studied pathogens stronger than Cinn-AgNP-PI in-vitro and on coated sutures. Dynamic light scattering (DLS), ultraviolet-visible spectroscopy (UV-Vis), Fourier Transform infrared spectroscopy (FT-IR), Raman, x-ray diffraction (XRD), microstructural analysis by scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS) confirmed the composition of TCA-AgNP-PI and Cinn-AgNP-PI. Smart solutions involving hybrid materials based on synergistic antimicrobial action have promising future perspectives to combat resistant microorganisms.

Project description:IntroductionSurgical site infections (SSIs) are among the most common and potentially serious complications after surgery. Staphylococcus aureus is a virulent pathogen frequently identified as a cause of SSI. As vaccines and other infection control measures are developed to reduce SSI risk, cost-utility analyses (CUA) of these interventions are needed to inform resource allocation decisions. A recent systematic review found that available SSI utilities are of "questionable quality." Therefore, the purpose of this study was to estimate the disutility (i.e., utility decrease) associated with SSIs.MethodsIn time trade-off interviews, general population participants in the UK (London, Edinburgh) valued health states drafted based on literature and clinician interviews. Health states described either joint or spine surgery, with or without an SSI. The utility difference between otherwise identical health states with and without the SSI represented the disutility associated with the SSI.ResultsA total of 201 participants completed interviews (50.2% female; mean age = 46.2 years). Mean (SD) utilities of health states describing joint and spine surgery without infections were 0.79 (0.23) and 0.78 (0.23). Disutilities of SSIs ranged from - 0.03 to - 0.32, depending on severity of the infection and subsequent medical interventions. All differences between corresponding health with and without SSIs were statistically significant (all p < 0.001).ConclusionThe preference-based SSI disutilities derived in this study may be used to represent mild and serious SSIs in CUAs assessing and comparing the value of vaccinations that may reduce the risk of SSIs.

Project description:IntroductionPost-craniotomy neurosurgical infections (PCNIs) significantly challenge daily neurosurgical practice, affecting patient outcomes and imposing economic burdens on healthcare systems. Despite advances in surgical techniques and infection control protocols, PCNIs still contribute to surgical-related morbidity and mortality.Research questionTo address these unresolved questions through a comprehensive literature review.Material and methodsWe conducted a detailed literature review using the keywords "Infection, Craniotomy, Neurosurgery," on PubMed, which yielded 2330 articles. Out of these, 171 were selected, based on relevance, and rigorously reviewed. The review aimed to answer thirteen major questions stemming from the management of PCNIs.ResultsPCNI incidences range from 0.7% to 8%, predominantly caused by gram-positive bacteria, especially Staphylococcus species. Significant risk factors identified include CSF leakage, emergency surgery, and certain tumour types, with infections typically manifesting post-discharge. Diagnostic approaches integrate clinical, radiological, and laboratory assessments, with advances in molecular diagnostics showing promising precision. While antibiotic prophylaxis remains effective, emerging resistance warrants cautious application. Surgical intervention is often indispensable for managing organ-space infections, with a trend towards bone flap preservation and one-step cranioplasty procedures in certain cases.Discussion and conclusionThe management of PCNIs remains a major challenge. There is a critical need for standardization of definitions and data reporting. Advancements in diagnostic and therapeutic strategies may bring future improvements in clinical outcomes, despite antibiotic resistance phenomena and the complexity of surgical decisions required. Ultimately, major engagement is aimed at refining and updating clinical protocols to improve and standardize the management of PCNIs.

Project description:PurposeSurgical site infection (SSI) remains one of the most common postoperative complications for patients with abdominal infections. This study aimed at investigating the effectiveness of high-volume normal saline (NS) irrigation in preventing postoperative SSI for patients with abdominal infections.MethodsIn this retrospective before-after clinical study, patients who underwent emergency laparotomy due to abdominal infections between Jan 2015 and Dec 2021 were included consecutively. A cohort of 207 patients with NS irrigation was compared to historical controls. A propensity score matching (PSM) with a 1:1 ratio was performed to reduce potential bias. The primary outcome was the 30-day SSI rate.ResultsIrrigation (n = 207) and control (n = 207) matched patients were statistically identical on baseline characteristics, perioperative, and intraoperative parameters. Irrigation patients had lower overall SSI rates (10.6% vs. 26.1%, p < 0.001), mainly due to reduction in superficial (4.3% vs. 17.9%) and deep (1.4% vs. 3.9%) SSIs, rather than space/organ SSIs (4.8% vs. 4.3%). Irrigation patients also had lower rates of incision seroma (4.8% vs. 11.6%, p = 0.012), shorter duration of antibiotics use (5.2 ± 1.7 d vs. 7.2 ± 2.0 d, p < 0.001), and unplanned readmission (1.0% vs. 8.7%, p < 0.001). Length of hospital stay showed a declining trend with irrigation intervention, while no significant difference was observed. Moreoever, logistic regression revealed that NS irrigationwas an independent protector against SSI (OR 0.309; 95% CI, 0.207-0.462; p < 0.001).ConclusionIntraoperative incision irrigation with high-volume NS is associated with a lower rate of SSI for patients with abdominal infections.

Project description:In this study, biologically synthesized AgNPs were found to be effective against six hospital prevalent bacterial species (Pseudomonas aeruginosa, Escherichia coli, Acinetobacter baumannii, Klebsiella pneumoniae, Methicillin-resistant Staphylococcus aureus and Enterococcus faecalis). AgNPs were deposited on the fabric and surgical blades using layer-by-layer and electrochemical deposition methods, respectively. The coated objects were characterized using scanning electron microscopy, X-ray diffraction and Fourier transform infrared spectroscopy and energy dispersive X-ray. Coated fabric samples and blades when tested against six above mentioned bacterial species were found to be effective for all of them. Antibiofilm activity of AgNPs coated blade and fabric was tested against P. aeruginosa and SEM images of post-treated fabrics and blades showed clear bacterial cell distortion and inhibition. Furthermore, washing durability test revealed that AgNPs were strongly attached to the surface of fabric even after 20 cycles of hospital laundering. This unlocks the way to several technologically relevant applications of AgNPs coated surfaces to reduce the risks of nosocomial infections and as a proof of concept; we demonstrated efficient antibacterial properties of AgNPs coated cotton fabric and surgical blades.
